Abstract
Abstract Silane-crosslinkable halogenated polymer composition and process of crosslinking the same. The silane-crosslinkable halogenated polymer composition contains a mixture including: 100 parts by weight of a halogenated polymer and about 0.1-20 parts by weight of an amino group-containing organic silane compound. The halogenated polymer composition silane-crosslinked is useful for the sheath and insulation of electric wires and cables and other moldings such as a hose.
